Manufacturer's description
Mobil Jet Oil CI is a high-performance aircraft-type gas turbine lubricant based on the proven Mobil Jet Oil II formulation, updated with additional additives for improved protection against rust and corrosion in severe operating environments. It is fully qualified against the Corrosion Inhibited (CI) classification of the MIL-PRF-23699 specification, for military and commercial applications requiring this level of performance. The lubricant is recommended for turbo-jet, turbo-fan, turbo-prop and turbo-shaft (helicopter) gas turbine engines in commercial and military service, and is particularly suited to aircraft-type gas turbines used in industrial or marine applications where additional protection against salt-water corrosion is needed. It is compatible with other synthetic gas turbine lubricants meeting MIL-PRF-23699, and with all metals and common seal materials (Viton A, Buna N, silicone) used in gas turbine construction, though mixing with other products is not recommended. Key features include retention of viscosity and film strength across a wide temperature range, chemical stability that reduces evaporation losses, and a low pour point that eases cold-weather start-up. Mobil Jet Oil CI is approved to MIL-PRF-23699-CI and listed on PRI-QPL-AS5780/SPC.
Applications
- Mobil Jet Oil CI is recommended for aircraft gas turbine engines of the turbo-jet, turbo-fan, turbo-prop, and turbo-shaft (helicopter) types in commercial and military service. It is also recommended for aircraft-type gas turbine engines used in industrial or marine applications where additional protection against salt water corrosion is required. Mobil Jet Oil CI is approved against the Corrosion Inhibited (CI) classification of U.S. Military Specification MIL-PRF-23699. It is also compatible with other synthetic gas turbine lubricants meeting MIL-PRF-23699. However, mixing with other products is not recommended because the blend would result in some loss of the performance characteristics of Mobil Jet Oil CI. Mobil Jet Oil CI is compatible with all metals used in gas turbine construction, as well as with F Rubber (Viton A), H Rubber (Buna N), and silicone seal materials.
